In this rapidly scaling-up program, survival and immune reconstitution were good; women and patients followed up in centers with longer experience had better outcomes; outcomes were similar in zidovudine/stavudine-based regimens and in efavirenz/nevirapine-based regimens. Decreasing the rate of loss to follow-up should now be the top priority in antiretroviral treatment rollout.
Entry into the programmeThe Aconda programme adopted a comprehensive family-based approach. Health-care workers were trained to offer HIV testing to every pregnant woman attending antenatal clinics and to encourage HIV-infected mothers to bring their children and partners with them for testing and counselling. Each pregnant woman with an HIV infection was immediately referred for an adult consultation. She then received PMTCT therapy, either a short regimen or ART depending on her clinical and immunological status, and underwent assessment at both antenatal and adult clinics. 18Children aged ≤ 15 years entered the Aconda programme in one of two ways: (i) after referral for HIV testing at the age of ≥ 6 weeks because their mother had been diagnosed with HIV infection and had received PMTCT therapy, or (ii) after HIV testing at a paediatric clinic following presentation with AIDS-related symptoms, even if they had not been previously classified as exposed to or infected by HIV and even if their parents had not participated in the Aconda programme. Standardized paediatric follow-upThe Aconda paediatric HIV care package included systematic paediatric HIV testing which varied according to the child's age. In those aged ≥ 18 months, the standard serum testing algorithm comprised a series of two rapid HIV assays: the Determine ® HIV-1/2 assay (Inverness Medical, Bedford, United Kingdom of Great Britain and Northern Ireland) followed by the Genie II ® HIV-1/HIV-2 assay (Bio-Rad laboratories, MarneLa-Coquette, France). 19 Children aged < 18 months were diagnosed virologically using a TaqMan HIV-1, ribonucleic acid (RNA), real-time polymerase chain reaction test (Hoffmann-La Roche, Basel, Switzerland) with a threshold of 300 copies/ml. 20 Children were regarded as having HIV-1 infections if, at any age, they tested positive for HIV-1 RNA in plasma at least once or if, at age ≥ 18 months, they were positive for HIV-1 on serum testing. Children who tested negative but who were still breastfeeding were defined as HIV-undetermined and were retested 2 months after the cessation of breastfeeding or at 18 months. A negative diagnosis was regarded as definite if it was made at least 2 months after the cessation of breastfeeding and children with this diagnosis were excluded from the programme.All children with a confirmed HIV infection were seen monthly and had unrestricted free access to antiretroviral drugs and comprehensive care. 21 In all children, whether on ART or not, the CD4+ T lymphocyte (CD4 cell) count and CD4 cell percentage were measured every 6 months. Plasma viral load testing was not performed routinely after the diagnosis of HIV infection, even in children on ART. Pulmonary radiographs were available for children whose history and symptoms suggested tuberculosis.Children initiated ART if they were either at World Health Organization (WHO) HIV/AIDS clinical stage 3 or 4 or at clinical stage 1 or 2 with impaired immunity (i.e. a CD4 cell percentage ≥ 25 at age < 12 months, ≥ 20 at 12-35 months or ≥ 15 at ≥ 36 month...
Objective To determine the rates and causes of first antiretroviral treatment (ART) changes in HIV-infected adults in Côte d'Ivoire. Methods We evaluated adults who initiated ART in an outpatient clinic in Abidjan. We recorded baseline and follow-up data, including drug prescriptions and reasons for changing to alternative first-line regimens (drug substitution for any reason but failure) or second-line regimens (switch for failure). Results 2012 HIV-infected adults (73% women) initiated ART. At baseline, 9% of all patients were on treatment for tuberculosis and 3% of women were pregnant. First-line ART consisted of 2 NRTIs (58% stavudine-lamivudine, 42% zidovudine-lamivudine) and efavirenz (63%), nevirapine (32%) or indinavir (5%). Median follow-up time was 16.9 months. During this time, 205 (10%) patients died and 261 (13%) were lost to follow-up. Overall, the rate of treatment modifications was 20.7/100 patient-years (PY). The most common modifications were drug substitutions for intolerance (12.4/100PY), pregnancy (4.5/100PY) and tuberculosis (2.5/100PY). The rates of intolerance-related substitutions were 17.9/100PY for stavudine, 6.3/100PY for nevirapine, 3.9/100PY for zidovudine and 0.1/100PY for efavirenz. Twenty percent of efavirenz substitutions resulted from pregnancy and 18% of nevirapine substitutions were related to tuberculosis treatment. Conclusions During the first months following ART initiation, a third of all treatment changes occurred for reasons other than intolerance to the drug or treatment failure. In Africa, drug forecasting is crucial to ensuring the success of HIV treatment programs. Drugs that do not require interruptions during pregnancy or tuberculosis treatment should be made more readily available as first-line drugs in sub-Saharan Africa.
Objective To estimate the probability of reaching the criteria for starting highly active antiretroviral therapy (HAART) in a prospective cohort of adult HIV-1 seroconverters in Abidjan, Côte d'Ivoire. Methods We recruited participants from HIV-positive donors at the blood bank of Abidjan for whom the delay since the estimated date of seroconversion (midpoint between last negative and first positive HIV-1 test) was < 36 months. Participants were offered early trimethoprim-sulfamethoxazole (cotrimoxazole) prophylaxis, twice-yearly measurement of CD4 count and we made standardized records of morbidity. We used the Kaplan-Meier method to estimate the probability of reaching the criteria for starting HAART according to WHO 2006 guidelines. Findings 217 adults (77 women (35%)) were followed up during 668 person-years (PY). The most frequent diseases recorded were mild bacterial diseases (6.0 per 100 PY), malaria (3.6/100 PY), herpes zoster (3.4/100 PY), severe bacterial diseases (3.1/100 PY) and tuberculosis (2.1/100 PY). The probability of reaching the WHO 2006 criteria for HAART initiation was estimated at 0.09, 0.16, 0.24, 0.36 and 0.44 at 1, 2, 3, 4 and 5 years, respectively. Conclusion Our data underline the incidence of the early HIV morbidity in an Ivorian adult population and provide support for HIV testing to be made more readily available and for early follow-up of HIV-infected adults in West Africa.Bulletin of the World Health Organization 2007;85: 116-123.

IntroductionExperts from the World Health Organization (WHO) and the United Nations Joint Programme on AIDS (UNAIDS) have estimated that at the end of 2005, 65% of the 39 million people with HIV worldwide were living in sub-Saharan Africa. 1 In Africa, only a small proportion of people who need highly active antiretroviral therapy (HAART) are currently being treated. However, the number who receive HAART has been increasing rapidly since 2004, and will continue to increase within the next few years thanks to national and international funds and initiatives.In 2003 and 2006, WHO experts defined criteria for initiating HAART in low-resource areas based on clinical criteria and, depending on the availability of laboratory facilities, either CD4 count or total lymphocyte count. Since cohort studies of patients from the time of HIV seroconversion are rare, little is known Methods PatientsRecruitment for the The Primo-CI ANRS 1220 prospective cohort started in 1997 in the HIV care clinic (FonSIDA clinic) of the Centre National de Transfusion Sanguine (CNTS), at the national blood bank of Abidjan.2 The study protocol was approved by the ethics committees of the national Ivorian program on AIDS and the institutional review board of the French Agency for Research on AIDS (ANRS).In the Côte d'Ivoire, blood donors are adult volunteers who are not paid. Blood donations are limited to five per year in men and four per year in women. ...
